Thomas Aquinas (1225-1274) and his legacy have become topics of intense debate in some evangelical circles today. There are those who look at him with great admiration and want to be identified as evangelical “Thomists” and others who think that Thomas is quintessentially a misleading theologian, being at the root of all the errors of Rome. Having this discussion in the background, the session will focus on Thomas’ doctrine of justification by faith, mainly drawing from his Summa Theologia. It will be an entry point into the theological universe of Thomas and will provide a case study of his larger theological work.
